数字电视广播对700MHz 5G移动通信网络的干扰与应对

Interference and countermeasure of digital TV Broadcast to 700MIHz 5G mobile communication network

700MHz是中国移动与广电共建共享的一张低频5G网络,借助700MHz频谱的优秀覆盖能力,广度和深度覆盖潜力价值巨大,当前700MHz频谱被广电数字电视广播占用,频率清退工作需要较长工作周期。文章重点分析700MHz数字电视广播对移动通信网络干扰的影响以及干扰规避解决方案对覆盖与用户体验提升的效果,并给出700MHz网络建设与完善的建议。

700MHz is a low-frequency 5G network jointly built and shared by China Mobile and China Broadcasting and Television.With the excellent coverage capability of 70OMHz spectrum,the coverage potential of breadth and depth is of great value,At presentthe 700MHz spectrum is occupied by radio,television and digital television broadcasting,and frequency clearing requires a long working cycle.This paper focuses on the analysis of the influence of 70oMHz digital television broadcast on mobile communication network interference and the effect of interference avoidance solutions on the improvement of coverage and user experience,and gives suggestions on the construction and improvement of 70oMHz network.
